# Interface: Options

Initial monitor display options.

## Remarks

These options seed the controller returned by [createMonitor](../index.md#createmonitor). Runtime
setters such as [Monitor.setValueRange](Monitor.md#setvaluerange) and [Monitor.setColormap](Monitor.md#setcolormap)
can update the mutable parts later.
